Abstract: The health benefits of omega-3 polyunsaturated fatty acids (n.3 PUFA) are generally recognized. Unfortunately,
in most western countries, the recommended daily intake of these compounds is rarely met. Therefore,
enrichment of commonly occurring foods can boost intake of these fatty acids. In this regard, eggs are an
interesting target, as they form an integral part of the diet. Their n.3 PUFA profile can bemodified through feed
supplementation. A traditional n.3 PUFA source to be added to hens' diet is flaxseed, a plant source rich in
á-linolenic acid. Alternatively, hens are often fed fishoil,which is rich in long chain n.3 PUFA eicosapentaenoic
acid (EPA) and docosahexaenoic acid (DHA). A more recent trend is feed supplementation with microalgae as a
source of EPA and/or DHA. In this paper, recent scientific literature concerning n.3 PUFA enrichment in eggs is
reviewed, giving an overview of advantages and disadvantages of the different approaches.
